Description/Action

COMMUNICATIONS PORT MISMATCH

One of the following conditions was detected:
• An ICN module (2030N)is installed but no
matching ICN block was found in the user
database. Matching includes slot numbers and
the module address switch setting, if not 'ANY'
in the ICN block.
• An RS-232 module (2033N) or an RS-485
module (2034N) is installed but no matching
MSC block was found in the user database.
Matching includes slot numbers/module type
and the module address switch setting unless
'ANY' is configured in the MSC block

INSTRUMENT SHUTDOWN FAULT

When the instrument was last powered, an
event occurred which caused it to shut down. It
is now locked in the DEFAULT state. The user
should investigate the cause of the shutdown
and try running the instrument again, if desired,
by writing ACK SHUTDOWN FAULT (value 1)
to IF block Attribute No. 141, Command (CMD).
This acknowledges that the user has seen the
information relating to a previous shutdown
fault and reinitializes the SHUTDOWN INFO
area. Until this is done, the instrument will not
accept commands which could cause it to
leave the DEFAULT state. Information
preserved at shutdown is stored in the non
checksummed save area in the battery backed
up RAM and is examined through the
configurator STATUS display activity.

MODULE SHUTDOWN FAULT

When the memory module was last used, the
instrument on which it was installed suffered a
shutdown fault. The shutdown information
preserved in the module is stored in volatile
RAM and is examined through the configurator
STATUS display activity. The battery backed
up RAM must be write protected (switch set at
READ ONLY) to prevent this data from being
overwritten when powered up for examination
on another instrument.

PROCESSOR WATCHDOG FAULT

When the instrument was last powered, the
processor got 'lost' and the watchdog timer shut
the instrument down. See Code 17,
INSTRUMENT SHUTDOWN FAULT.

SPURIOUS EVENT FAULT

When the instrument was last powered, the
processor was interrupted by an unexpected
event (i.e. it had no handler to respond to the
event) and the instrument therefore shut down.
See Code 17, INSTRUMENT SHUTDOWN
FAULT.
